CROSS-REFERENCE TO RELATED APPLICATION

The present disclosure claims the priority of the Chinese patent application filed on Sep. 10, 2020 before the CNIPA, China National Intellectual Property Administration with the application number of 202010945649.6 and the title of “METHOD AND SYSTEM FOR MONITORING SWITCH ON BASIS OF BMC, AND DEVICE AND MEDIUM”, which is incorporated herein in its entirety by reference.

FIELD

The present disclosure relates to the field of switches, and more particularly to a baseboard management controller (BMC)-based switch monitoring method, a system, a computer device, and a readable medium thereof.

BACKGROUND

As a separate system separate of a network operating system (NOS) of a central processing unit (CPU), a BMC has its separate processor and memory, and may operate separate of the NOS. In case of crash or hardware failure of the NOS, the BMC may still operate and perform management on the NOS or hardware resource diagnosis.

At present, most of BMCs are single chips. Switches become more and more powerful, for example, some switches involve information of four line cards and hundreds of sensors, and it is also necessary to monitor information of temperatures, voltages, currents, fan speeds, and the like of other devices. Therefore, the BMC needs much more time to poll these devices during monitoring than monitor other small switches, and is slow to sense exceptions of processing capability of display cards, chips, etc. Moreover, during firmware upgrading of the BMC, it is necessary to first ensure the normality of an upgrading function and suspend other functions for example monitoring, etc., and the switch cannot be monitored if having an exception during the suspension, so it is impossible to monitor the switch around the clock. A conventional BMC has a single core where functions are realized in parallel, and when a firmware upgrade service is required, other services are required to be suspended. The BMC cannot be restarted by itself in case of an exception in its monitoring process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make the object, technical solutions, and advantages of the present disclosure clearer, the embodiments of the present disclosure will further be described below in detail in combination with specific embodiments and with reference to the drawings.

It should be noted that expressions using “first” and “second” in the embodiment of the present disclosure are intended to distinguish two different entities or different parameters with the same name, therefore, “first” and “second” are only for the sake of convenience of expression, and should not be understood as limiting the embodiments of the present disclosure, which is no longer specified in the subsequent embodiments.

Based on the above object, a first aspect of the embodiments of the present disclosure proposes an embodiment of a BMC-based switch monitoring method. FIG. 1 is a schematic diagram of an embodiment of a BMC-based switch monitoring method according to the present disclosure.

As shown in FIG. 1 , the embodiment of the present disclosure includes the following steps.

In S1, a multi-core BMC is virtualized into a plurality of logical computers such that each core operates separately.

In S2, in response to start of a switch, functions of the switch are migrated into a first core of the multi-core BMC for start, and other cores of the multi-core BMC are monitored based on a second core of the multi-core BMC.

In S3, in response to that a new service is received by the switch is detected, whether the new service is a firmware upgrade service is determined.

In S4, the new service is allocated to the second core in the multi-core BMC for operation, in response to that the new service is the firmware upgrade service.

In the embodiment of the present disclosure, a multi-core BMC chip is virtualized into a plurality of logical computers. Under normal conditions, monitoring functions of the BMC chip are placed in a single core, and this core is used to scan a utilization of a CPU of the BMC chip in real time and scan a state of a current monitoring process in real time. When the utilization of the CPU of the BMC chip reaches a preset threshold, subsequent processes, services, and so on, are started in a third core and a fourth core. A service related to firmware upgrade and a real-time monitoring process are implemented separately in a second core. When a BMC, a basic input output system (BIOS), a complex programming logic device (CPLD) and a field programmable gate array (FPGA) are upgraded on the BMC, a normal monitoring service of the BMC is not affected, and the processing capability to handle exception is improved.

The multi-core BMC is virtualized into a plurality of logical computers such that each core may operate separately. Each core in the multi-core BMC may be virtualized into a logical computer. In other embodiments, two or more cores in the multi-core BMC may be virtualized into a logical computer.

In response to start of a switch, functions of the switch are migrated into a first core of the multi-core BMC for start, and other cores of the multi-core BMC are monitored based on a second core of the multi-core BMC. After the switch is started, the functions are started in the first core by default, and other cores in the BMC are monitored through the second core.

In response to that a new service is received by the switch is detected, whether the new service is a firmware upgrade service is determined. The new service is allocated to the second core in the multi-core BMC for operation, in response to that the new service is the firmware upgrade service.

In some embodiments, the method further includes: whether a utilization of the first core exceeds a preset threshold is determined, in response to that the new service is not the firmware upgrade service; and the new service is allocated to the first core for operation, in response to that the utilization of the first core does not exceed the preset threshold. For example, the preset threshold may be 80%. Whether the utilization of the first core exceeds 80% is determined. If the utilization of the first core does not exceed 80%, the new service is still allocated to the first core for operation.

In some embodiments, the method further includes: whether a utilization of a third core exceeds the preset threshold is determined, in response to that the utilization of the first core exceeds the preset threshold; and the new service is allocated to the third core for operation, in response to that the utilization of the third core does not exceed the preset threshold. Still in the above example, if the utilization of the first core exceeds 80%, whether the utilization of the third core exceeds 80% is determined. If the utilization of the third core does not exceed 80%, the new service may be allocated to the third core for operation. In this manner, if the utilization of the third core exceeds 80%, whether a utilization of a fourth core exceeds 80% is determined.

In some embodiments, the method further includes: whether the utilization of the first core exceeds a second preset threshold is determined, in response to that the utilizations of the cores in the multi-core BMC except the second core exceed the preset threshold; and the new service is allocated to the first core, in response to that the utilization of the first core does not exceed the second preset threshold. For example, the multi-core BMC has four cores, and the utilizations of the first core, the third core, and the fourth core exceed 80%. Whether the utilization of the first core exceeds the second preset threshold is determined, which may be, for example, 95%. If the utilization of the first core does not exceed 95%, the new service may be allocated to the first core for operation.

In some embodiments, the method further includes: reception of the new service is suspended, in response to that the utilizations of the cores in the multi-core BMC except the second core exceed the second preset threshold. Still in the above example, if the utilizations of the first core, the third core and the fourth core exceed 95%, it indicates that there are too many services in the switch and it is necessary to suspend reception of new services, and reception of the new services may be resumed after the utilizations of the cores are less than a preset threshold.

In some embodiments, the step that the new service is allocated to the second core in the multi-core BMC for operation includes: whether the firmware upgrade service in operation exists in the second core is determined; and input of the new service to the second core is suspended, in response to that the firmware upgrade service in operation exists in the second core. When a second firmware upgrade service is received before completion of a previous firmware upgrade service, input of any new firmware upgrade service to the second core may be suspended, so as to avoid impact on the previous firmware upgrade service.

In some embodiments, the method further includes: in response to that an exceptional process on other cores exists is detected, the exceptional process is restarted.

It is to be particularly pointed out that the respective steps in the respective embodiments of the above BMC-based switch monitoring method may be mutually intersected, replaced, added, and deleted. Therefore, these reasonable permutations, combinations, and transformations about the BMC-based switch monitoring method shall also fall within the scope of protection of the present disclosure, and the scope of protection of the present disclosure should not be limited to the embodiments.

In some embodiments, the system further includes a fourth determining module, configured to determine, in response to that utilizations of the cores in the multi-core BMC except the second core exceed the preset threshold, whether the utilization of the first core exceeds a second preset threshold, and allocate the new service to the first core in response to that the utilization of the first core does not exceed the second preset threshold.

In some embodiments, the system further includes a suspension module, configured to suspend reception of the new service, in response to that the utilizations of the cores in the multi-core BMC except the second core exceed the second preset threshold.

In some embodiments, the execution module 6 is configured to determine whether the firmware upgrade service in operation exists in the second core, and suspend input of the new service to the second core in response to that the firmware upgrade service in operation exists in the second core.

In some embodiments, the system further includes a restart module, configured to, in response to that an exceptional process on other cores exists is detected, restart the exceptional process.
